Title:
LUBRICATING GREASE HAVING A HIGH WATER-RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2005/108532
Kind Code:
A1
Abstract:
The invention relates to lubricating greases containing at least one thickening agent and at least one lubricating oil. The lubricating grease contains at least one polymeric structure improver that can be obtained by polymerizing monomer compositions comprised of: a) 0 to 40 % by weight, with regard to the weight of the monomer compositions for producing the polymer structure improvers, of at least one (meth)acrylate of formula (I), in which R represents hydrogen or methyl, R' represents a linear or branched alkyl radical with 1 to 5 carbon atoms; b) 40 to 99.99 % by weight, with regard to the weight of the monomer compositions for producing the polymeric structure improvers, of at least one (meth) acrylate of formula (II), in which R represents hydrogen or methyl and R2 represents a linear or branched alkyl radical with 6 to 30 carbon atoms; c) 0.01 to 20 % by weight, with regard to the weight of the monomer compositions for producing the polymeric structure improvers, of acid groups containing monomers or salts thereof, and; d) 0 to 59.99 % by weight, with regard to the weight of the monomer compositions for producing the polymeric structure improvers, of comonomers.
